lmown that I,A.SAHEI1L.BEMIS, a citi- "l of the United States, residingat Pueblo, is the county of Pueblo and State of Coloredo, have inventedcertain new and. useful lrnprovemcnts in Molds for Ornamental ArtificialStone and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the. figures of reference markedthereon, which form a part of this specification.

My invention relates to imitation-stone composition, molds for the sameand plateglass facings, in which the com osition of broken glassplaster-of-paris, san hydraulic cement, an water which when driedproduces a stone (M31181 in solidity and beauty to My invention greatlyfacilitates the art of producing an apparent polish to ortions of thestone by the use of my pane s of plate glass, which are helddn thecomposition so as to appear to be-a polished surface of the stone.Inscriptions for monuments may be heaut'rfully marked out by etching orpaintmg on the face of the glass panels next the com osition.

T e objects of my invention are, first, to facilitate the forming ofstone uniformly; sec- 0nd, to cheapen the cost of stones that are to beused as polished stones for the (purpose of ornamentation, and, third topro use an ornamental stone for monuments and building purposes inlocalities Where ranite or marble is scarce or high in rice. attainthese objects by the use of t e materials described in conjunction witha suitable mold that is easily and quickly made in any desired fOTll, aave-monument and a mold for the same eing illustrated in theaccompanying draws, in whichigure 1 is a perspective View of a grave--monument. Fig. 2 is a vertical sectional View of Fig. 1 on the line a,b. Fig. 3 is a cross section in perspective throu h the center of mymold suitable for fornnng the grave-monument in Fig. 1, and Fig. 4 is aKlan View of my turnbuckle-brace used for olding the platssglass panelsin place.

My invention is described as follows: To produce myrstonc, take brokenand screen it t screen the roduct through a twelve-mesh screen, ,retaminthat art which does not pass through tlle twe ve-mesh screen and mix itwith an or ual part of plasterof-paris. Take one part 0 this mixture,two parts of clean sharp sand, and one part of hydraulic cement and mixthe whole thoroughl together while dry. Then add water until the mixturehas the consistency of thin mortar or until it will run easily. For amixture to produce a marble effect use the same mixture as above,-exceptuse the finer lass that has passed through the twelve-mes screen,handling the mixture in the same manner as the mixture for producingranite.

To further employ t 1e composition'above described, I use a mold of myown construction, as shown. in Fig. 3. The sides of said mold areconstructed of thin shcet-metal plates 1 and 1 to the inner faces ofwhich are fastened by suitable screws 2 Wooden strips 10 for the pur oscof furnishing a hold for the cement 3 ant 3 to the plates, the comentbeing used as a part of the mold. Said cement is ap lied Wet and ofproper consistency to stan when applied and to be formed in such shapethat the mold when completed will form a stone or monument of anydesired sha ue. The ends a of the mold are built of the same materialand in the same In armor and the cement applied the same as in the sidesof the mold. When the said ce-- ment has sufficiently dried, the twoends 4 are placed between the sides 1 and l at the edges thereof, andthe parts are held securely together by clamps 5. Those clamps Work onthe outside of the mold, their ends formed into bowed necks, and turnover and impings against the outer faces of said sides, sair, bowednecks being provided with tightening thumb-screws 5. When the mold isthus finished and read for use, the said compoundis poured into t 1emold and allowed to set until the stone so molded will stand. Then thesaid clamps 5 are removed, and the sides and ends of the mold areremoved, leavin the finished stone ready for use.

0 produce apparently polished surfaces, I use plate'glasspanels. Saidplate-glass panels are held in lace in the mold by being set on fine 6,(see lg. 3,) in which case I set the glass panels against the inner faceor faces of the protrudf part 9 of the cement lining 3 and 3% To oldsaid plate-glass panels 7 ough a four-mesh screen. and. 1 firmly whilethe mixture is being applied, I no use a turnbucklebrace, (seeFig. 4,)which ha ve beenmadb; and Ithotefire-donot claim consists of aturnbuckle 11, right and left such acombina'tion broadly; but 30 threadsturning into said buckle and fiat-faced What I do claimias invention,and deheads 14 and 15, secured one to each of the sire to securebLetters atent, is-
